Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a profile gear jaw clamp. Background Technology

[0002] Machining generally requires the use of fixtures. When machining the end face of rod-shaped parts, the parts need to be placed vertically. Furthermore, specific machining operations may require defining fixed angles for the rod-shaped parts.

[0003] Because of the smooth surface of rod-like components, it is difficult to determine the angle of the rod-like components themselves when clamped. However, some rod-like components will cooperate with gear components, which can be taken advantage of. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a profile gear jaw clamp to limit the angle when clamping rod-like components.

[0005] To achieve the above objectives, the present invention provides a profiled gear jaw clamp, comprising a base, a pushing mechanism disposed on the base, a fixed block disposed on the base, a movable block disposed on the base and poweredly connected to the pushing mechanism, a locking block disposed on the upper end of the fixed block, the locking block having an internal gear; a gear fitted onto a rod-like component to be processed, the gear meshing with the internal gear to restrict the rotation of the rod-like component; the lower part of the rod-like component is inserted into the space between the fixed block and the movable block, and the movable block, through movement, locks the lower part of the rod-like component.

[0006] As a further improvement of this application, the pushing mechanism includes a rotating screw and a driven block. The base has a moving cavity inside, the top of the moving cavity has a square moving groove, and the side of the moving cavity has a threaded hole. The driven block is disposed in the moving cavity, the top of the driven block has a protrusion, the protrusion extends out of the moving cavity through the moving groove and connects with the moving block. The rotating screw has a round rod structure, and its outer surface is partially provided with external threads. The part with external threads mates with the threaded hole. The rotating screw moves along the axial direction by rotating. The part of the rotating screw inserted into the moving cavity is movably connected to the driven block.

[0007] As a further improvement of this application, the driven block is provided with a connecting hole, the longitudinal section of the connecting hole is convex, the diameter of the inner part is larger than the diameter of the opening, the rotating screw is inserted into the connecting hole, and the diameter of the end of the rotating screw inserted into the connecting hole is larger than the diameter of the rotating screw located at the opening of the connecting hole.

[0008] As a further improvement of this application, the top of the fixing block is also provided with an alignment strip, and the end of the rod-like component to be processed is provided with an alignment groove. The alignment strip is inserted into the alignment groove so that the gear and the internal gear are aligned and meshed.

[0009] As a further improvement of this application, a triangular protruding block is provided on the side of the protrusion, and an embedding groove is provided at the bottom of the movable block. The embedding groove cooperates with the triangular protruding block to realize the connection between the protrusion and the movable block.

[0010] As a further improvement of this application, the bottom surface of the internal gear is higher than the upper surface of the movable block.

[0011] The beneficial effects of this invention are as follows: The rotation of the rod-like component to be machined is limited by the engagement of internal gears and gears; the fixed block and movable block engage to hold the rod-like component, facilitating subsequent machining. Some rod-like components will engage with gear components, utilizing the gears inherent in the rod-like component itself to limit its angle, achieving a better driving effect.

[0024] like Figures 1-3 As shown, a contour gear jaw clamp includes a base 1, a pushing mechanism mounted on the base 1, a fixed block 2 mounted on the base 1, a movable block 3 mounted on the base 1 and poweredly connected to the pushing mechanism, a locking block 4 mounted on the upper end of the fixed block 2, the locking block 4 having an internal gear 5; a gear is fitted onto a rod-like component to be processed, the gear meshing with the internal gear 5 to restrict the rotation of the rod-like component; the lower part of the rod-like component is inserted into the space between the fixed block 2 and the movable block 3, and the movable block 3, through movement, locks the lower part of the rod-like component.

[0025] The internal gear 5, in conjunction with the gear, restricts the rotation of the rod-like component to be machined. The fixed block 2 and the movable block 3 engage to hold the rod-like component in place, facilitating subsequent machining. Some rod-like components will cooperate with gear components, utilizing the gears inherent in the rod-like component itself to limit its angle, achieving a better driving effect.

[0026] To achieve the driving operation, the driving mechanism includes a rotating screw 11 and a driven block 12. The base 1 has a moving cavity 13 inside, and the top of the moving cavity 13 has a square moving groove 14. The side of the moving cavity 13 has a threaded hole 15. The driven block 12 is disposed in the moving cavity 13, and the top of the driven block 12 has a protrusion 121. The protrusion 121 extends out of the moving cavity 13 through the moving groove 14 and connects with the movable block 3. The rotating screw 11 has a round rod structure with external threads on its outer surface. The part with the external threads mates with the threaded hole 15. The rotating screw 11 moves along the axial direction by rotating. The part of the rotating screw 11 inserted into the moving cavity 13 is movably connected to the driven block 12.

[0027] In order to drive the driven block 12 to move together, the driven block 12 is provided with a connecting hole 122. The longitudinal section of the connecting hole 122 is convex, and the diameter of the inner part is larger than the diameter of the opening. The rotating screw 11 is inserted into the connecting hole 122. The diameter of the end of the rotating screw 11 inserted into the connecting hole 122 is larger than the diameter of the rotating screw 11 at the opening of the connecting hole 122.

[0028] In order to limit the installation angle of the rod-like parts to be processed, the top of the fixing block 2 is also provided with an alignment strip 16, and the end of the rod-like parts to be processed is provided with an alignment groove. The alignment strip 16 is inserted into the alignment groove so that the gear and the internal gear 5 are aligned and meshed.

[0029] To prevent the movable block 3 from being lifted directly from the vertical direction, a triangular protrusion 123 is provided on the side of the protrusion 121, and an embedding groove 31 is provided at the bottom of the movable block 3. The embedding groove 31 cooperates with the triangular protrusion 123 to realize the connection between the protrusion 121 and the movable block 3.

[0030] To prevent mutual interference, the bottom surface of the internal gear 5 is higher than the upper surface of the movable block 3.
